HOISTING DEVICE FOR VEHICLE BODIES.

Application filed February 26, 1927. Seria1 No. 171,10'1.

This invention, generally stated, relates to a novel hoisting device andhas more espeial relation to a novel hoisting device used in conjunctionwith a vehicle body, particularly of the motor truck type.

The leading object of the present invention may be said to reside in ahoisting device of the character stated in which is incorporatedsimplicity of design, cheapness of construction, and efficiency ofoperation and in which the vertical over-all dimension of the hoistingdevice is maintained as small as possible.

` A further obl'ec-t of the present invention is to provide a structureof the character above stated in which separable body and chassis armsare assembled in a novel manner and provided with rollers therebetweencarried by a novel yoke and its adjuncts, for positively coacting withthe respective lower and upper edges of said arms for sepa-rating thesame. Y

It further consists of a novel construction of a yoke and rollers and asheave carried thereby, for effecting the actuation of th chassis andbody arms or levers.

Other and further objects reside in thel provision of general details ofconstruction, arrangement and'combination of parts for attaining theresults sought by the foregoing objects. i v

The invention consists of the novel yconstruction hereinafter describedand finally claimed.

For the purpose of illustrating my invention I have shown in theaccompanying'A drawings one form thereof which is at present preferredby me, since the'same has been found in practice to give satisfactoryand reliable results, although it is to vbe understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof, and in which: Fig. irepresentsa view in side elevation of avmoto'r truck ychassis equippedwith it embodying the invention;

ignates the side rails of a truck or vehicle chassis and 2 designatesthe rear wheels thereof. Fixed to the rear of each chassis rail 1 as byrivets, bolts or the like 3 is a bracket 4 having bearings, in whichbearings is rotatably mounted a horizontally disposedy shaft or bodyhinge 5. The shaft 5 passes` through a pair of oppositely dis' posedangular plates 6, which are attached to and support a truck body 7, sothat the latter is pivotally mounted with respect to the chassis rails1, as is clearly shown in Fig. 2. i

A description will now be given of the means. fortilting the body 7 withrespect to the chassis rails` 1. Fixed. to the chassis .rails 1 is atransverse base plate 8. Fixed to this horizontally disposed plate 8which-v .straddles thel chassis rails 1 are brackets9 spaced apart, asclearly shown in Figs. 1 and 2, and in which brackets is rotatablysupported' a horizontal shaft 10. Carried by and fixed to this shaft 10are a pair of inner chassis arms or lever armsI 11, through the outerends `of each of which passes a horizontally arranged hinge-pin 12. Theouter ends of the hinge-pin 12 pass through a pairof arms 13 whose rearends are piv` otally secured by the hinge-pin 14 to brackets 15 fixed tothe underside of the truck body 7. The front or right hand end of eacharm has' therein a. horizontally disposed shaft 16 mounted upon which isa roller or sheave 17,

said rollervbeing provided with opposed bearings 18 which rotate freelyon said shaft 16, the function of the roller or sheave 17, beinghereafter explained. Carried by the arms `11 is a U-shaped member oryoke 19,

eachl arm of which is slotted as at 20 and has adjustable relation withthe arms 11 by means of bolt or stud connections 21. said bolts or studspassing loosely through the slots 20. vThe y0ke 19 carries a shaft 22upon Y' the ends of which are mounted pairs of opposed freely rotatablerollers 23, apen which rollers 23 inthe movement er the may 7 sea-0m@ages of. are arms 1a taaie-muy shown in Fig. 2, thus elevating thetruck engage. Carried by the shaft 22 and interposed between the rollers23 a sheave 24, as clearly shown in Fig. 3. Having fixed relation withrespect to the hinge-pin 12 or other desired attachment near the ends ofarms 11 as by they pin 25 is one end of a cable 26, Which passesrearwardly aro-und sheave 24, thenceV forwardly around sheave 17, andthence rearwardly around a drum 27, as clearly shown in Fig. 3, Whichdrum is mounted upon an operatingr shaft 23 provided with pavrl andratchet mechanism 29 to prevent retrograde movement of the parts duringa hoisting period. Carried by the arms 13' is' atransversely disposedshaft 30 uponvvhich ismounted a sheave 31. The purpose of this sheave orroller 31 is to guide the cable- 26 during a hoisting period, the cable213 normally being engaged bythe roller or sheave 31. as is clearlyshown in Fig. 1. The shaft 28 of the drum or Winch 27 is provided with ahandle 32 for manual operation in the hoisting of the body 7, but

4it' is obvious that said shaft 28 may be operatively connected with:any conventional power mechanism of a *motorl truck for the hoistingoperation of body 7 and any other form of winch may be employed.

In' operation' the rollers mounted as they are upon the ends of theshaft 22 will so bear against the bottom edges of the arms* 13 and topedges of arms 11, that when by means of the Winch a pull is exertedonthe cable 26er the latter is shortened, said rollers 23 bearingagainst the underside of a`rmsf13y and top edges of' arms 1.1 will beforced towards pin 12 and cause said arms 11 and 13 to .sepaate at theirfree ends, as clearly body 7,. the yoke 19 moving` from the position`seen in Fig. 1- into the position seen in Fig. 2. As thismovcmentcontinues, the movement of the rollersi2f3'and-t'hc sheave 24therebetween is altered for a given speed of cable, and as this movementbecomes slower,y the movement of sheave 17 is accelerated; sothat 'for agiven forceezierted at the ivmclr 27 the lifting and hoisting. force atthe hinge-pin or pivotv points 14 becomes su'b. sta'ntially constant AstheV cable is shortened it will be apparent that tfhe arms 11T and vr13Willl be forced apart at their free ends carrying pins10 and 14,andsincethepin. 10'is lined with respect to the chassis it` Willbe'clear that pin 14 will be forced upward` ly and backwardly,itsmovementberingcontroll'ed' by the body hinge 5, so'tliat'thepartswill assume the' position' seen in" Fig; 2.

It will'v be understood-,that the chassis arms `11 and the bodyarms 13withy their Vcoacting'rollers 23 can housed-singly or inmultiple of anynumber of'y pairs, tivvovof eaclrunit being shown herein. i Especial`attent-:ion isdire'cted to thenove'l collocation; and assembly of thechassis arms 11 and the longer Lesa555 body arms 13 in conjunction withthe rollers 23, yoke 19, sheave 24 and their adjuncts, since by thisconstruct-ion an effective and povverful hoisting mechanism' is providedWhich will actuate the loaded body 7.

It is to be noted that a separate roller reversed end for end to attainthev same result. In other Words, the device functions to lift the bodyand the precise or exact path it Will/followv is determined by thehinUe-p'ointofthe body.` H
